Studies of the resistance of species of Passiflora to Fusarium wilt (F. oxysporum F. Passiflora)

Abstract

It is possible to obtain a degree of resistance to Fusarium wilt in the purple passion fruit (Passiflora edulis) but the resistance so far located has only been sufficient to delay infection. This would be of little value commercially, where a high level of resistance is required to suit a perennial plant. Some other species and varieties of Passiflora possess good resistance to the disease and certain strains of the golden passion fruit (P. edulis f, flavicarpa) possess characters suited to their use as resistant rootstocks.
